[0001] 1. Technical Field

[0002] The present invention relates to a connecting structure between aconnector and a flexible cable enabling to separate a connector insertedportion and a band portion continued thereto in a lengthwise directiondevised not to accidentally get out as a connector is fixing theconnector inserted portion therein, and relates to a flexible cable.

[0003] 2. Related Art

[0004] An existing flexible cable has had a problem that the number oflead wires of plural rows buried therein is fixed, and so flexiblecables in response to the number of pins of connectors have to beprepared in the same sort and the same number as those of theconnectors.

[0005] Besides, a flexible base is described in the Examined JapaneseUtility Model Application Publication No. Hei5-1095. As shown in FIGS.4A, 4B and 5, this has a structure where a V-shaped edge slit 101 b isdirected to a part of the flexible base to be divided, while V-shapedcutting portions 101 a, 101 c are directed to sides of the flexiblebase, the portions extending the distals thereof till slight distancefrom the distal of the v-shaped edge slit 101 b, and a copper foil 102is shielded around the V-shaped cutting portions 101 a, 101 c and theslit 101 b.

[0006] However, as seen in FIGS. 4A and 4B, there is another problemthat the widths of the cutting portions 101 a, 101 b are large and bothedges are shaped in V, so that breakage easily happens at these partsand are probably separated carelessly.

DETAILED DESCRIPTION OF THE PREFERERED EMBODIENTS

[0023] Explanation will be made to an embodiment of the flexible cableaccording to the invention, referring to the attached drawings.

[0024]FIG. 1 shows embodied flexible cables of the invention, and FIG.1A is a front view thereof, FIG. 1B is a front view of a condition thatthe flexible cable of one end is branched in fork at the connectorinserted portion into a band portion and the connector inserted portionof another end, and FIG. 1C is a side view of the same.

[0025] The flexible cable of the embodiment has, as seen in FIGS. 1A, Band C, a structure where perforating slits are formed in the lengthwisedirection between the lead wire 1 and the lead wire 1 of the bandportion 3 continued to the connector inserted portion 2 buried with thelead wires of the plural rows, the perforated slit is made long in theconnector inserted portion 2 and short in the band portion 3, and theflexible cable is separated at the perforated slits 4, and is separableas needed into plural pieces of 2 pieces or more.

[0026] As shown in FIG. 1B, the flexible cable is separated from theperforated slits 4 of the band portion 3 and the connector insertedportion 2 of one end, so that the band portion 3 and the connectorinserted portion 2 are separated in to plural pieces more than the forkat the connector inserted portion 2 of the other end not separated.

[0027] As shown in FIG. 1C, the flexible cable F is formed in a mannerthat the center lead wire 1 is pasted with tapes 5 at both sides and anoutermost plate 6 in the thickness.

[0028] Therefore, according to the flexible cable F of the embodiment,the same flexible cable F is separated at the perforated slit andconnected to the connector C having different pin number (refer to FIG.2), and is not separated accidentally when being unnecessary.

[0029] The perforated slits 4 in the lengthwise direction are made longin the connector inserted portion 2 and short in the band portion 3, sothat a thick connector inserted portion 2 difficult to be separated iseasily divided.

[0030]FIG. 2 is a partially perspective view of the connecting structureof the connector and the flexible cable according to the embodiment ofthe invention.
